Constant temperature and humidity laboratory widely used cotton, wool, chemical fiber, paper, packaging, chemicals, tobacco manufacturers and inspection, commodity inspection, Xianjian, museums and other departments, constant temperature and humidity laboratory is the manufacturer of the product quality inspection and control and circulation of goods in the field of infrastructure, quality inspection gatekeeper. Constant temperature and humidity laboratory coming through a lab of some special equipment, technical methods and construction technology to meet the indoor temperature and humidity conditioning and testing using a standard atmospheric requirements. In accordance with the relevant ISO and GB standards, testing textiles, textile raw materials, paper, cardboard and other paper products and the quality of the physical commodity items must be carried out under standard atmospheric conditions. Standard atmospheric testing of textiles and textile raw materials at ISO139-1973 "Textiles - humidity and temperature and humidity testing standards" and GB 6529-198 "textile conditioning and testing using standard atmospheric" standard temperature of 20 ℃±1 ℃, relative humidity 65% ± 2%; standard atmospheric paper, paper products and cardboard commodity inspection in accordance with ISO187-1990 "Pulp, paper and cardboard - atmospheric temperature and humidity test and control procedures and treatment standards and experimental treatment temperature and humidity steps "and GB10739-1989" standard atmosphere "pulp, paper and paperboard sample processing and testing standards, the temperature23 ℃±1 ℃, relative humidity of 50% ± 2%.
